SUMMARY.

a. Waveshapes that do not follow the conventional pattern of the

sine wave are called nonsinusoidal waves.

b. An aperiodic wave is a wave which appears at irregular

intervals or only once.

c. A period wave is a wave that is repeated at constant

intervals.

d. Nonsinusoidal waves can be analyzed by either the frequency

response method of analysis or the transientresponse method of

analysis.

e. A steady state is a period when there is no change in voltage

or current.

f. The frequencyresponse method analyzes a waveform by

determining the number, amplitude, and frequency of sine waves

required to reproduce it.

g. The rate at which a waveform is repeated is known as

repetition frequency, and is equal to the frequency of the

fundamental sine wave required to produce it.

h. The second harmonic is equal to twice the frequency and half

the amplitude of the fundamental frequency.

i. When forming a waveshape, the maximum number of harmonics that

must be included varies inversely with the pulse width.

j. The transientresponse method analyzes the response of a

circuit to nonsinusoidal voltages.

k. A transient is a brief change in voltage or current.

l. Transient time is the period of time during which the

transient occurs.

m. A square wave consists of a fundamental frequency and its odd

harmonics.

n. A rectangular wave consists of a fundamental frequency and

establish the desired reference level.

o. A sawtooth wave consists of a fundamental frequency and its

even and odd harmonics.
